### Why is this important?

A combobox combines a text input element and a popup element that helps the user set the value of the
input. The text input element must be a single line text field with an appropriate role, otherwise 
assistive technologies may not be able to present and control the content correctly. 

The WAI-ARIA 1.1 combobox pattern was not supported by browsers. The WAI-ARIA 1.2 pattern is best
supported by browsers and assistive technologies.

<div id="locSnippet"></div>
